All the people I know who started Feast For Crows are having a hard time remembering who is who in this rather epic tale. Someone has been kind enough to write a short primer to bring you back up to speed. On the same website, you can find a database of characters, houses and geography. If you have lots of time on your hands you can read summaries of each chapter of each book. For those of you who have not yet started this series of books, I imagine you are either fascinated or horrified that someone has taken this much time to analyze these books.
